Your 12-Month-Old: First Steps, and Using Things the Way They Are Meant
By the Growbaby team · Published Aug 4, 2026
Written against AAP, CDC and WHO guidance. How we write these guides
At a glance
- Using a brush on hair or a cup to drink shows your baby has learned what things are for.
- Simple turn-taking games are now genuinely two-way.
- Standing unsupported usually comes before walking unsupported.
- First steps commonly land around now, with a wide normal range either side.
- Sleep is typically 12 to 16 hours per 24, and the second nap usually holds for a while yet.
The first birthday gets treated as a finish line and it is mostly a bookmark. The genuinely new thing this month is functional play: your baby brushes their hair with a brush rather than banging it, holds a cup to their mouth, puts a phone to their ear. They have worked out what objects are for, which is a different kind of knowing than what objects do.
First steps often arrive around now. If they do not, that is still firmly within normal; the usual guidance is to check in if a baby is not walking at all by about 18 months.
What is new this month
Functional play is the genuinely new thing. Your baby brushes their hair with a brush rather than banging it, holds a cup to their mouth, puts a phone to their ear. Knowing what an object is FOR is a different kind of knowing than what it does, and it only comes from watching you.
First steps often land around now, and the normal range either side is wide enough that a baby walking at nine months and one walking at seventeen are both unremarkable. The first birthday is a bookmark rather than a finish line.
Week by week, in the app
Our paediatric specialist wrote one thing to notice and one thing to try for every week of the first three years. Here is what this month covers. The app works out which week your child is in from their birth date and brings each one to you on the day.
- Week 49Your baby is Using Objects for Their Intended Purpose
- Week 50Your baby is Playing Simple Games
- Week 51Your baby is Standing Independently
- Week 52Your baby Takes Their First Steps
This week, for your baby
Growbaby works out which week your baby is in from their birth date and brings that week's activity to you on the day, so you are not looking up where you are. Plus adaptive soothing for the nights and Growy for the questions in between.
